I HINGE FOR BOOK COVERS Filed Sept. 6, 1939 v 2 Sheets-Sheet 2 Aiiorneys Patented Nov. 12, 1940 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates-to a hinge means for connecting two parts of abook cover together.

The general object of the invention is to provide a hinge to which covermembers and leaves of a book may be fastened.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts to behereinafter fully described, illustrated in the, accompanying drawingsand specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure lis a view looking toward the front of a device constructed in accordancewith this invention.

Figure 2 is a section on line 2-2 of Figure 1.

go Figure 3 is a rear view with parts in section.

Figure 4is a section on line 4--4 of Figure 3.

Figure 5 is a perspective view of the rear member.

Figure 6 is a perspective view of one of the g5 hinge members.

In these drawings, the numeral l indicates the rear member which has itstop rounded, as shown at 2, and a longitudinally extending groove 3 isformed in the under edge of the member adja- 30 cent, the front facethereof for receiving portions of the back member 4 of the book orcover, the parts being connected together by glue or in any othersuitable manner. The under or outer face of the member 4 forms a:continuation of the 35 lower or under edge of the member I, as shown inFigure 2. Notches 5 are formed in the upper portion of the member I andare spaced apart and said notches extend through the upper edge 2 andthrough the front and rear faces and substantially cylindrical parts 6of hinges I fit in said notches. Each cylindrical part is formed with ahole 8 and holes 9 are formed in the member I and extend inwardly fromthe ends thereof and intersect the notches. Hinge pins III are passedthrough the holes 9 and the holes 8 to pivotally connect the leaves ofthe hinges with the member I. Each leaf is fastened to a top or covermember H such as by means of the nails I! or in any other suitablemanner.

50 Holes I! are formed in the member I and pass from the rear facethrough the front face and these holesare adapted to receive a cord orstrip M which around the leaves ll of a book or the like, as shown inFigure 2 and also in Figure 4. Of course, the device can be used as aleaf binder by having suitable means on the member 4 for holding theloose leaves in the usual or any suitable manner. 5 As shown in Figure2, the member I slopes slightly forwardly and upwardly with its frontand rear faces parallel sloped as shown at l6 and this arrangementthrows the 'pivotal points Ill slightly forwardly so that the free edgeof the 10 cover member H will substantially align with the front edge ofthe member 4 when the member I l is resting on the member 4.

As will be seen the hinge has but one leaf with a. circular part at oneend thereof which is piv- 15 oted to the supporting member.

It will also be seen that a book or leaf holder as shown in the drawingsis of attractive design and when made of wood will have many advantagesin holding notebooks, regular books, loose leaves and the like as thecomparatively heavy v cover member II with the back member 4 willprevent the leaves from curlingand will hold the leaves pressed togetherand the member 4 will form a firm foundation when one is writing on 5the leaves in the device and is holding the device on his lap or knee. v

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It" is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts provided thatsuch changes fall within the scope of the appended claim.

What I claim is: o

A combined backing strip and hinge for use in book binding comprising abacking bar having a bottom side provided with an undercut front edgefor fitting over a cover panel, and a 40 top side provided with stransversely rounded and grooved rib extending along the same andforming one member of a hinge, hinge leaves for attachment to a secondcover panel and having hinge eyes fitting in said grooves, pintlesextending into said rib and through said eyes, saidstrip being-provided.with transverse apertures therein intermediate said sides thereof, and aflexible tie member extending through said apertures for securing bookleaves to said strip intermediate said cover panels.
